Application filed October 10, 1913. Serial No. 794,371.

the objects of the invention are to provide an adjustable stanchion andfurther to provide a simple, efficient and reliable stanchion.

Referring to the drawings which accompany this specification and form apart hereof, on which drawings the same reference characters are used todesignate the same elements wherever they may appear in each of theseveral views, and which drawings illustrate an embodiment of thisinvention, Figure 1 is an elevation of a stanchion, parts being shown insection; Fig. 2 is an elevation of the stanchion seen from one side;Fig. 3 is a section taken on the line a-a on Fig. 1, looking inthedirection indicated by the arrows; and Fig. 4 is a section taken onthe line bb on Fig. 1, looking in the direction indicated by the arrows.

The embodiment of the invention illustrated by the drawings andhereinafter specifically described is what I consider the best andpreferred form of its embodiment but it will be apparent that mechanicalchanges can be made without departing from my invention.

Referring specifically to the drawings,the reference numeral 1designates one upright and 2 the other upright. Preferably theseuprights arecomposed of tubes and the upright 1 is U-shaped with theupper end longer than the lower end to allow for the openin of thestanchion in the manner to be herelnafter described. Bifurcated, curvedcastings 3 and t are secured in the ends of upright 2 and adjustablecollars 5 and 6 are clamped on the upper and lower horizontal parts ofupright 1 by set screws 7 and 8, or other suitable fastening means. Theunder side of the upper horizontal part of upright 1 is provided with aslot 9 into which projects the latch 10 which is pivoted in thebifurcation of casting 3 on pivot 11. The latch has a recess 12 toreceive the lower part of collar 5 to lock the upright 2 againstmovement either toward or away from uprlght 1. he latch is retained inengagement with the collar 5 by the s ring 13 but can be disengagedtherefrom y pressing the handle part it of the latch toward the upright2. The latch is provided with a lJ-hook 15 to engage with an adjacentmemher (not shown) to prevent swinging or twisting of the stanchion whenit is opened. A stop 16 provided with a slot 17 in its lower side isfastened in the end of the hori-' zontal, upper, tubular part of upright1 by a set screw 18 or other suitable fastening means and a stop-pin 19passed through the latch prevents the latch from being entirelywithdrawn from the tube when the stanchion is opened.

The collar 5 is provided with apertured lugs 20 and 21 for suspendingthe stanchion and the collar 6 is provided with apertured lugs 22 and 23for fastening the lower end of the stanchion in any ordinary orpreferred manner. The collar 6 has extensions 2% and 25 carrying acollar part 26 which is provided with a lug 27 extending between theparts of the bifurcated casting a and this casting is pivoted to thislug by the pivot 28. To adjust the stanchion to make it larger orsmaller to accommodate difierent sized necks of animals, set screws 7and 8 are loosened and collars 5 and 6 are both moved the requireddistance in the proper direction and the set screws are then tightened.The collar 5 is provided with a rib Patented Mar. it), rate,

29 which projects into the slot 9 and prevents the slot being closedupon the latch 10 and binding the same when the set screw 7 istightened.

What is claimed is:

1. An adjustable stanchion composed of i an upright provided with upperand lower der side, adjustable collars on said upper and lowerhorizontal portions, an upright pivoted to the lower collar, and a latchpivoted to the last mentioned upright extending into said slot andadapted to engage the upper collar.

3. An adjustable stanchion composed of an upright provided with upperand lower horizontal portions the upper of which is tubular and providedwith 'a slot in its under side, ad ustable collars on said upper andlower horizontal portions, an upright pivoted to the lower'collar, alatch pivoted to the last mentioned upright extending into said slot andadapted to engage the upper collar, a stop provided with a slot in. theend of the upper horizontal portion of the meaoae first mentionedupright, and/a stop-pin carried by said latch.

into said slot and means for securing said collar upon said firstmentioned upright.

In witness whereof I hereto afl'ix my signature in presence of twowitnesses.
